Abstract (en)
[origin: US2004187930A1] A pressure reducing fluid regulator having a housing with a flange including a plurality of ear-shaped protrusions is disclosed. Each of the protrusions includes at least one aperture configured to receive fastener such that the circumferential spacing between first and second fasteners is less than the circumferential spacing between the second fastener and a third fastener. The regulator includes a valve having a valve seat, a valve disc, a valve stem coupled to the valve disc and a valve guide that holds the valve stem. A lever having a first end coupled to the valve stem and a second end coupled to a diaphragm applies a force to the valve stem in a direction that is non-parallel to the longitudinal axis of the valve stem to cause the valve stem to frictionally engage the valve guide. The valve stem includes a stop that limits travel of the valve stem and disc toward the valve seat.
